Who it's for

Is this you?

Medical Students

Build the statistical literacy now that will underpin every journal article, evidence-based guideline, and research project you encounter throughout your career.

Resident Physicians

Move beyond passively trusting published p-values — critically appraise the RCTs and cohort studies that shape the clinical guidelines you follow daily.

Clinical Researchers

Design rigorous studies with justified sample sizes, build valid regression models, and write statistical analysis plans that hold up under peer review.

Public Health Professionals

Apply the epidemiological study design, multivariable modelling, and meta-analysis skills that drive credible population-level research and policy recommendations.

Academic Faculty

Sharpen your command of survival analysis, confounding, and reporting standards so you can mentor trainees and review manuscripts with genuine statistical authority.

Grant Applicants

Learn to write a defensible statistical analysis plan and power calculation — the sections reviewers scrutinise most closely — to strengthen every funding application you submit.

A note from your teacher

Dr. J Raymond ABK

Dr. J Raymond ABK

If you've ever read a clinical paper and felt a quiet unease when you reached the statistics section — scanning the p-values, trusting the authors' conclusions, and moving on — I want you to know that's not a personal failing. It's the entirely predictable result of a medical education system that treats statistics as a prerequisite to survive rather than a discipline to actually learn.

I've worked with clinicians and researchers at every stage of training, and the pattern is remarkably consistent: brilliant, analytically capable people who can reason through a differential diagnosis with precision but go strangely passive the moment a hazard ratio or a confidence interval appears. The issue is never aptitude. It's always that no one ever built the framework properly — from probability and inference through to multivariable modelling — in a way that connected to the clinical world they actually inhabit.

That's exactly what this curriculum is designed to do. We start where understanding actually begins: with the logic of statistical inference, the meaning of a distribution, the difference between a population parameter and a sample estimate. We don't skip those foundations because they seem basic — we build them carefully, because every advanced concept you'll encounter in the literature sits on top of them. From there, we move methodically through hypothesis testing, effect size interpretation, test selection, regression modelling, survival analysis, and critical appraisal, always with real biomedical research as the context. By the time you're working through Cox proportional hazards regression or reading a forest plot from a Cochrane review, you'll have the scaffolding to understand not just what the output says, but why the method was chosen, what its assumptions are, and where it can go quietly wrong.

I'm also not going to pretend the goal is purely academic. You need this literacy to design defensible studies, write statistical analysis plans that survive peer review, present findings to colleagues who will challenge them, and — most importantly — read the evidence base that informs your clinical decisions with genuine critical judgment. Those are practical, career-long skills, and this curriculum is built to deliver them.

If you're ready to stop hoping no one asks about the statistics and start being the person in the room who actually understands them — come in. The work is rigorous, the examples are real, and the clarity is worth it.
